Guinea Pig Halloween

Guinea pigs are friendly pets and tend to err on the quiet side, but once you get to know them—as only a human companion can—their unique personality starts to shine through. With an abundance of Halloween costumes designed for guinea pigs to choose from this year, there's probably a spooky or adorable Halloween costume that's perfect for bringing out your tiny pal’s inner self.

Guinea pigs can easily be startled, so we kept the scary looks to a minimum with our costume recommendations and focused on get-ups related to activities that guinea pigs and their owners might share. They might even let out a signature excited "wheeking" sound when you introduce them to their costume!

We've also looked for guinea pig costumes that are easy to fit and designed for guinea pigs of all shapes, sizes, and fur lengths. Here are the best Halloween costumes for guinea pigs.

Our Top Picks

Best Overall

Thrills and Chills Corn on the Cob Small Pet Costume

Corn on the Cob


What We Like
  • It’s corn!

  • Soft and stretchy fabric

  • Cute little corn hat included

  • Adjustable strap around the body

  • Elastic ribbon for headpiece

What We Don't Like
  • You can’t add butter

What better way to celebrate all that is corntastic than with a corny costume for your guinea pig!

Not everyone has to like it for it to be the best, but our top pick is this corn on the cob costume. It has knobs made of polyester and spandex, so it’s soft and stretchy. The adjustable Velcro belt goes around your guinea pig’s tummy to keep the costume in place, and the little corn hat features an elastic strap. Guinea pigs love eating corn, so we think they’ll love dressing up as corn for Halloween!

If you are looking for something a little sweeter, we also like this candy corn knit costume, but it's priced a little higher than our top picks.

What We Like
  • One size fits all

  • Easy to put on

  • Affordable

  • Elastic ribbon keeps hat in place

  • No Velcro included

What We Don't Like
  • Does not come with a small baguette as a prop

Guinea pigs are cute and delicate, so adding a little hat for Halloween goes a long way. Our top pick has a certain je ne sais quoi that will have your guinea pig feeling like the star of Emily in Paris–or at least a Parisian mime! This petit beret is chic and easy to slip on and off, and the elastic chin strap, with an adjustable toggle, will keep it perched on your guinea pig’s head without being too tight. (And just so you know, "the guinea pig" in French is le cochon d'Inde.)

We also symbolically tip our cap to this tiny cowboy hat, which will fit in alongside your guinea pig’s hay, and we give our compliments to this teaspoon-sized chef's hat.

Best Fruit Costume

HYLYUN Strawberry T-Shirt for Guinea Pigs - 2 Pack

Strawberry T-Shirt for Guinea Pigs


What We Like
  • Soft and stretchy fabric

  • Sold as a pair with one pink and one red strawberry

  • No Velcro

  • Easy to put on

What We Don't Like
  • Doesn’t include a head accessory like a small leaf

  • No option to purchase just one

Their food is typically served in pellet form, but guinea pigs are herbivores, meaning they feast on fruits and veggies. As the old adage goes, “You are what you eat,” so this Halloween we recommend dressing up your guinea pig like a piece of fruit they love. Our favorite is this fuzzy strawberry costume. It’s stretchy and soft, making it comfortable and easy to put on and take off. It also comes as a pair with a pink and a red top, so if you have two guinea pigs, you’ll be all set!

We also like this banana pouch and this pineapple hut. Both will invite your guinea pig to sit inside and participate in Halloween. And don't forget about our overall best costume, corn on the cob. Depending on whom you ask, corn could technically be here among the fruit!

Best Costume With Wings

Thrills and Chills Magical Unicorn Small Pet Costume

Unicorn Costume for Guinea Pigs


What We Like
  • Iridescent horn and wings

  • Furry tail and mane included

  • Adjustable strap around the body

  • Elastic ribbon for headpiece

What We Don't Like
  • Velcro has the potential to stick to fur

  • Thicker material might make your guinea pig feel like it is wearing two winter coats

You’ll watch with delight as your guinea pig soars through the air—in the safety of your hands—with this magical unicorn costume. The silvery wings and dreamy tie-dye coloring are eye-catching, but the furry tail and matching hat, complete with horn, mane, and ears, make this our top pick for faux flights this Halloween.

The costume features Velcro straps under the chin and around the body, and an elastic ribbon to secure the headpiece, so your guinea pig will comfortably transform into an ethereal mystical creature right before your eyes. For gliding guinea pigs with other preferences, we also like this striking dragon costume and this cheery bumblebee costume, but the headpiece gives more coverage, and some guinea pigs might not tolerate it.

Best Witch Costume

Witch Costume for Guinea Pigs with Broom

Etsy FoxyHatsUK

What We Like
  • Easy to put on

  • Tiny broom accessory is included

  • Very affordable

  • No Velcro

What We Don't Like
  • Does not include a tiny book of spells

It’s the broom for us—just picture your guinea pig's little fingers latching on! This witch hat and broom combination is our best pick for a guinea pig witch costume, because, on top of being adorable, it’s easy to get onto your guinea pig. The hat is made of felt, and you can select between two ribbon colors, purple or yellow, and the dollhouse-sized broom is made to scale from golden silk sorghum.

While some might consider a witch to be scary, we believe that witches can be good or bad (according to The Wizard of Oz anyway), and a guinea pig as a witch for Halloween is beyond good. We also like this colorful witch costume, which reminds us of the Sanderson Sisters from Disney’s Hocus Pocus, and this witch hat with a cape for added flair.

What We Like
  • Adjustable strap around body

  • Emphasizes adorable shape of guinea pigs

What is shaped like an oblong and has tiny limbs? A Minion and your guinea pig! Our favorite movie-inspired costume is this Minion getup. The costume features the quintessential overalls look from the Minion characters with sewn-on buttons. An attached hood, with the iconic Minion goggle, makes it easy to adjust on your guinea pig's head. A strap with Velcro gently wraps around the midsection and will secure the costume in place on your guinea pig. If this look is too mischievous for you, we also like this fierce , along with links for Wonder Woman look and stealthy Batman disguise.

Jack O' Lantern Pumpkin Small Pet Bandana


What We Like
  • Bandana style is easy to slip on and off

  • Festive without any fuss

Your guinea pig will look gourd-geous with this tiny jack o’ lantern bandana.

Simply place the bandana around your guinea pig's neck, and loosely tie the ends of the ribbon together. We also like this pumpkin style that wraps around the belly, and this bite-sized pumpkin hat made of yarn.

Final Verdict

The corn on the cob costume is our top recommendation, because it will transform your guinea pig into “a big, beautiful lump with knobs on it." It’s also easy to get on and off, and it’s very affordable. If you are looking for something even easier, the beret is a simple, yet sophisticated, costume that can have multiple interpretations. It can even inspire your fall/winter wardrobe!

What to Consider When Selecting a Guinea Pig Costume

Be Gentle

Guinea pigs should always be handled with care. Never try to force anything onto a guinea pig. Stay calm, and give your guinea pig little treats. Guinea pigs have particularly sensitive faces, so it's important to make sure the costume isn't blocking their ability to smell or impeding their breathing in any way. Remember that rubber bands, additional string, and other quick-fix methods to try and keep a costume attached should never be used with a guinea pig. If you can't make the costume work, don't force it, and try a different one next year!

Measure Carefully

While some Halloween costumes are designed specifically for guinea pigs, many are meant to be used by a range of small pets, including rabbits and rats. This means it is important to pay close attention to fitting information and to make proper measurements in advance, using a fabric measuring tape.

The girth of your guinea pig will help to determine whether a wrap-around costume is suitable. Carefully place a tape measure ribbon around their belly. It should be a little loose and able to accommodate their fur or hair. You can also wrap a piece of string around and then measure on a standard ruler.

  • Can guinea pigs wear costumes?

    Yes, but only for short increments of time, and they should never be left unattended while in costume. Make sure the costume does not completely cover your guinea pig's head or rear end. They are very delicate, so always handle your small pet with care.

  • Can guinea pigs communicate?

    Yes, a guinea pig will make a variety of sounds and movements to let you know how it is feeling. A unique "wheeking" sound is made to express excitement, while a shriek or hiss can indicate fear. It's important to note body language and sound together.
